To all whom it may concern:

Be it known that I, Josnrn H. CHAMP, a citizen of the United States, resident of Cleveland, county of Ouyahoga, and State of Ohio, have invented anew and useful Improvement in Motors, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle so as to distinguish it from other inventions.

The object of the invention is to provide an improved motor.

. The invention consists of the means hereinafter described, and particularly pointed out in the claims.

The annexed drawings and the following description set forth in detail, certain mechanism embodying the invention; such disclosed means constituting but one of various mechanical forms in which the principle of the invention may be used.

Figure 1 is a side elevation of a double acting hydraulic air compressor. Fig. 2 is a longitudinal horizontal section of the water cylinder, the top of the primary valve chamber being broken away, and showing the primary valve in top plan. Fig. 3 is a side elevation of the water cylinder opposite to the side shown in Fig. l; the primary valve chamber and certain other mechanism being shown in longitudinal vertical section. Fig. 4 is a side elevation of the Water cylinder and the main valve mechanism casing; certain mechanism being shown in dotted lines, and other mechanism being in longitudinal vertical section. Fig. 5 is a vertical transverse section of the water cylinder, on line 0c9c of Fig. 4; the casing of the main valve mechanism being partly in section and partly in side elevation. Fig. dis a vertical transverse section of the water cylinder, on line y-y of Fig. 4, with the main valve mechanism casing in similar section. Fig. 7 is a transverse vertical section of the water cylinder,

on line z2 of Fig. 4, with the main valve mechanism casing partly in section and partly in side elevation.

The double acting hydraulic air compressor is provided with a water cylinder A, and with an air cylinder B. On the outlet side of the water motor, a primary valve chamber O is located, at the end of the latter next to the air cylinder. Primary valve piston mechanism D reciprocates longitudinally in such valve chamber, and has rigidly secured on its piston rod (1, the two end pistons d d and the intermediate piston valve d Three annular channels 0, c, c surround the valve chamber, and connect therewith at various points. On the inlet side of the water motor, the casing E of the main valve mechanism is located; the spaces within such casing including differential cylindrical sections located in vertical line with each other; the upper cylindrical section 6 being of the smallest relative diameter; the middle cylindrical section e being of the next larger diameter; the bottom cylindrical section 6 being of the largest diameter. Upper cylindrical section e has annular channel e surrounding it, and connecting therewith at various points. Middle cylindrical section c has annular channel e surrounding it, and connecting therewith at various points.

Main valve mechanism F consists of rod f having rigidly secured thereto three members, namely: piston valve f secured to the upper portion of rod f, and working in cylindrical section e; piston valve f secured to the middle portion of rod f, and working in cylindrical section 6; piston f secured to the lower portion of rod f, and working in cylindrical section 6 A passage G has its lower portion in constant free communication with the lower portion of piston cylindrical section 6 by connection 9 which is always below the piston f of the main valve mechanism, the upper portion g of such passage G connecting with annular channel 0. One end of a passage H has a depending branch h connecting with annular channel 6 the outer end of such passage H has connection 'h with the interior of the outer end of the water cylinder. A passage I has its lower extremity connecting with annular channel 6 the upper portion of such passage connecting directly with the interior of the inner end of the water cylinder. Annular channel 0 of the primary valve chamber connects by passage 0 with the top of piston cylindrical section c (Fig. 5). Ann'ular channel c of the primary valve chamber connects with outlet J, by intermediate passage j (Fig. 7). One end of passage L, formed in the lower lon itudinal portion of the water cylinder she 1,- has connection Zwith the interior of the water cylinder; its other end connects with vertical passage 1, which latter empties by Way of assage j into outlet J; said connection Zis ocated, near the middle of the length of the water cylinder, relatively to the two pistons K and K on piston rod 7c so that such connection Z is always between such two pistons. The function of said passage L is to pass to the outlet J such volume of the motive fluid as is discharged from the two ends of chamber 0 into cylinder A through the connection m 1 immediately hereinafter described. One end of assage M has connection m with the interior of the water cylinder, at a point further from the air cylinder than is connection Z; the opposite end of passage M communicates with the end of the primary valve chamber C nearer to the air cylinder. One end of passage N has connection 11, with the interior of the water cylinder, at a point nearer the air cylinder than is connectlon Z; the opposite end of passage N communicates with the end of the primary valve chamber C further from the air cylinder. The inlet 0 is formed in the side of the casing of the main valve mechanism, on the opposite side of the motor from outlet J; it connects by passage 0 with the upper portion of the piston chamber 6 it also connects by angular passage 0 with the upper portion of to valve chamber 0. The air compressing cyinder has working therein a piston K rigidly secured on piston rod 7c; such rod having longitudinal reciprocating movement in suitable fluid tight packings respectively of the water cylinder and the air cylinder. Such two cylinders are joined together by bolts 1).

The operation of the foregoing described mechanism is as follows; assuming the main valve mechanism to be in uppermost position, as shown in Fig. 6. The pressure water passes from inlet 0 to the outer end of the water cylinder,by'way of passage 0, piston cylindrical section 6 valve cylindrical section e, annular channel 6 passage 71, passage H. Thereupon such pressure water forces piston K towards the air cylinder, so that pistons K and K have positions as shown in dotted lines of Fig. 2; thereby establishing pressure water communication with the end of the primary valve chamber nearer the air cylinder,by way of passage M. The primarv valve D is thereupon moved to it's furthest possible position from the air cylinder, as shown in dotted lines in Fig. 3; annular channels 0 and c are thus thrown into communication by the intermediate portion of the valve chamber C; permitting the water beneath piston f in piston cylindrical section e to pass to outlet J,by way of connection 9, passage G, passage 9, annular channel 0, a part of primary valve chamber 0, annular channel 0 passage 7'. Main valve mechanism thereupon drops into position shown indotted lines of Fig; 6; piston valve f shutting off the flow of pressure water from valve cylindrical section 6 to annular channel 0. Pressure water then passes. from inlet 0, to the inner end of the water cylinder,by way of passage 0 into the top of top valve cylindrical section e, thence through annular channel a and passage I. Piston K therefore moves away from the air cylinder, so that the two pistons K and K assume positions shown in full lines in Fig. 2. within the water cylinder passes, through opening n, and passage N, to the end of the primary valve chamber C further from the air cylinder. The primary valve D therefore moves to position nearest to the air cylinder, as shown in full lines in Fig. 3. Annular channels a and c are thus thrown into communication; the pressure water against upper. face of piston f thereby passing to bear against the lower face of piston f 3 (Fig. 6),by way of passa e 0 annular channel 0, part of valve cham er C, annular channel c,passage g, passage G, connection 9. Water then passes to outlet J from the inner end of the water cylinder,.by way of passage I, annular channel 6 top valve cyl- Then, the pressure water indrical section 6, valve cylindrical section 5,

passage j.

While I have herein described the invention as applied to compressing air, it is plain that the same may be applied to forcing or lifting water, or in analogous operation on other suitable fluid. So too, any suitable fluid may be employed as the actuating fluid, instead of water, in cylinder A.
